Get current rowindex from RowFilter include

Question

I have filtered a JTable with following RowFilter and it works fine:

RowFilter<AbstractTableModel, Object> rowFilter = new RowFilter<AbstractTableModel, Object>(){
    public boolean include(RowFilter.Entry<? extends AbstractTableModel, ? extends Object> entry){
        String cellValue = entry.getValue(0).toString();
        boolean isRowIncluded = cellValue.startsWith(filterText) ? true : false;
        return isRowIncluded;
}
};

But I am facing an issue. I have to apply the same filter logic to TreeTable. I have a custom table and table model extended from AbstractTableModel. I need to filter the rows and show its parents rows (parent rows may not satisfy isRowIncluded).

How can I achieve the functionality with my existing row filter?
